Build an unsigned swap transaction for the best route
Build an unsigned swap transaction for the best route. Builds an unsigned transaction for the selected route. Compare it with a fresh quote, validate every returned transaction field, obtain explicit signing approval, and broadcast it through the selected chain's RPC. The compatibility parameters permit and usePermit2 are ignored. For an ERC-20 source, approve the router in tx.to for at least srcAmount before executing the returned transaction.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
